30 mL of 0.1 M HCI is titrated with 0.1 M CH3NH₂ (Ka = 2.0 x 10-11) solution. Calculate the pH after adding 40 mL of CH3NH₂ to initial acid 10.2 5.51 1.48 12.0 9.81

state if true or false 1. Considering that concentration and the size of sample container are the same, a sample with a higher molar absorptivity will have a higher TRANSMITTANCE than a sample with the lower E (molar absorptivity). 2. Considering that concentration and the size of sample container are the same, a sample with a higher molar absorptivity will have a higher ABSORBANCE than a sample with the lower E (molar absorptivity). 3. The higher the concentration of a sample is the higher the transmittance will be. 4. Spectrophotometry is the study of how light interacts with matter 5. During an absorbance reading, light must pass through the opaque side of the cuvette. 6. Distilled water is an acceptable blank solution for any sample

The question and infromation should all be there to answer question. the Answer should be malonic acid. Also Please write the steps and answers without using any computer commands or scripts, just write it normal.
